Evolução do uso e valorização das espécies madeiráveis da Floresta Estacional Decidual do Alto-Uruguai, SC.

Abstract: Com base nas informações coletadas em 41 entrevistas feitas junto a madeireiros, ex-madeireiros e colonizadores, determinou-se quais as espécies potencialmente madeiráveis, o valor de uso e a valorização econômica das espécies madeiráveis para os remanescentes da Floresta Estacional Decidual na região do Alto--Uruguai, SC, desde o início da colonização daquela região. A diversidade de espécies florestais de uso madeirável conhecida popularmente na região foi de 63 espécies. Contudo, em termos de dominância ess… Show more

“…Radiation filtered through tree canopies has a different spectrum, with a lower red:far red ratio due to the selective absorption by leaf pigments (MARTINEZ-GARCIA et al, 2010). Many plants respond to a lower red:far red ratio in incident light with increased apical dominance (SCHMITT;WULFF, 1993). Lower PAR also increases apical dominance (ALMEIDA; MUNDSTOCK, 2001), with the result that the light conditions in our study might have converged to reduce tillering.…”

“…The most commonly used timber species in southeastern Brazil is eucalyptus, but farmers there are exploring alternatives, including some native species (RUSCHEL et al, 2003;CARPANEZZI et al, 2010).…”

“…Eucalyptus is the main tree species used in these forest systems in Central and Southeast Brazil. With the interest of producers in diversifying the forestry base by introducing native species (RUSCHEL et al, 2003;CARPANEZZI et al, 2010), other species have been tested in these systems, in both the Atlantic Forest and Amazon biomes (CARVALHO et al, 1997;DIAS, 2005;SOUCHIE et al, 2005), mainly using leguminous nitrogen-fixing species, aiming to maintain or rehabilitate pasture productivity.…”

“…Esta Fabaceae -Caesalpinioideae vem sendo extraída de forma maciça e suas populações naturais estão sofrendo diminuição significativa (NICOLOSO; FOGAÇA; ZANCHETTI, 2001;RUSCHEL et al, 2003), tanto por conta do extrativismo desordenado, quanto às suas sementes germinarem de forma lenta e irregular (CARVALHO, 1994). Este atraso na germinação ocorre por causa de uma barreira mecânica que confere dormência às sementes, devido à impermeabilidade do tegumento.…”
